CMC can determine respective smallest packet delay metrics associated with respective priority levels and respective DRBs based on respective remaining packet delay budgets of respective downlink data packets. CMC can apply respective weight values associated with the respective priority levels to the respective smallest packet delay metrics. For each DRB, CMC can determine the DRB delay metric of the DRB based on the smallest weighted packet delay metric associated with the DRB.
